MICROBIOLOGY EXERCISE Five. Metabolic Activities of Bacteria
One. OBJECTIVES:
One. Learn how to use differential and selective media to identify bacterial species.
Two. Perform the following biochemical tests and understand how they work: carbohydrate fermentation, casein hydrolysis and citrate utilization.
Three. Relate the results of the tests performed to the different types of metabolic activities carried out by individual bacterial species.
